Machining

VERTICAL MACHINING CENTERS

The majority of our work is done with equipment with a work envelope of 50 x 25 x 25 inches, but larger parts can also be machined on larger equipment, or with multiple setups. Three-axis equipment is the most extensively utilized equipment across many industries. We rarely find the additional complexity is cost effective, however, 4 and 5 axis equipment are available if other solutions are not cost effective. The precision and accuracy of any machining is a function of the equipment, fixturing and cutting tools. AMFAS' use of the best equipment for the job at hand allows for tight tolerances in any production part that we fabricate.

SCREW MACHINING

Most work fits within a 50mm (2 inch) diameter capability. Larger diameters typically move to chuck type lathes or short-bar automatic machines. AMFAS can accommodate almost any size and type of machining.

Modern screw machines under 25mm typically use swiss type cutting and holding methods. This method was developed many years ago by Swiss machinery builders which allows the bar stock to move in/out of the cutting area using a sliding headstock. The headstock is the collet that supports the bar material. The cutting of material is done immediately at the collet support to minimize the flex of the bar material. This allows long thin parts to be cut with great precision. AMFAS sources use the latest machine and tooling technology to provide cost effective screw machine parts.

SECONDARY MACHINING

Secondary machining involves all other possible machining that could be performed on a component. While modern machines can typically drill cross holes or machine flats on the primary machine, it is often more efficient or even necessary to perform secondary machining operations when the part is highly complex. Our sources have a variety of secondary machines capable of providing a variety of machining operations.
